Well, portability in a quality as with my software takes a lot of effort.

Speaking for cdrecord, the change not really needed as no writer uses
something differnt from lun 0.

 

      

Does this mean that if a real SCSI burner is used with a LUN of >0 it 
doesn't work with your software, or some part of the standard says it 
must be zero, or you have never seen one jumperd for non-zero, or ???
    

I would call it (close to) impossible to jumper the LUN of such a SCSI
device at all! ;-)

One can imagine burners w/ disc change mechanism, although I've never seen one,
and the LUNs will be hardwired...

  

I have some (admitedly old) CD readers with micro-jumpers about 2mm wide to set the LUN, and I've used SCSI drives with pads to solder a jumper, so I would not be surprised to find that some SCSI burners still have LUN jumpers. I have to take apart a pait of systems with SCSI burners in the next few days, a Phillips 2600 and a Sony(?) in the other. I'll look, now that you have me curious.

So there are Plextor and Matshita drives in that one, as well as a 4mm DAT and some 8mm tapes which are unplugged. I'll look for LUN jumpers when I rebuild two systems into a single functional system.
In any case, my question is if the software would support such.

Ha, I can ssh into the system which is still up, and it tells me:

  It seemed like a good idea at the time
